Data for: Chemical characterization of PM10 samples collected simultaneously at a rural and an urban site in the Caribbean coast: local and long-range source apportionment

This data was used to identify the main sources of PM10 in rural and urban environments in Cienfuegos, Cuba. Using this dataset, a source apportionment study employing PMF 5.0 coupled with the conditional bivariate probability function (CBPF) and concentration weighted trajectory (CWT) was performed as an integrated approach in order to evaluate the local and long-range (Sahara dust) contributions to PM10 for the first time in the studied region.
